The Boston Bruins scored four unanswered goals in the second period to take the lead 5-3 in the second period of their Sunday's matchup against the Pittsburgh Penguins.
Brad Marchand scored his 17th of the season to make it 3-2, and then exactly one minute later Noel Acciari tied the game with his sixth goal of the year.
David Pastrnak then scored his 17th of the season to give back the lead to Boston!
David Backes gave a two-goal lead to the Bruins when he scored his eight of the season.
Penguins head coach Mike Sullivan pulled Tristan Jarry from the game after this goal, to replace him with Matt Murray.
Evgeni Malkin scored for the Penguins only four seconds before the end of the period, to cut Boston lead to only one goal.
Wow! What a crazy period!
